Genome-wide identification and comparative evolutionary analysis of the Dof transcription factor family in physic nut and castor bean.

ABSTRACT: DNA-binding with one finger (Dof) proteins comprise a plant-specific transcription factor family involved in plant growth, development and stress responses. This study presents a genome-wide comparison of Dof family genes in physic nut (Jatropha curcas) and castor bean (Ricinus communis), two Euphorbiaceae plants that have not experienced any recent whole-genome duplication. A total of 25 or 24 Dof genes were identified from physic nut and castor genomes, respectively, where JcDof genes are distributed across nine out of 11 chromosomes. Phylogenetic analysis assigned these genes into nine groups representing four subfamilies, and 24 orthologous groups were also proposed based on comparison of physic nut, castor, Arabidopsis and rice Dofs. Conserved microsynteny was obs
